Summary

Heart rate variability(HRV) and electroencephalography(EEG) has been used widely in anesthetic practice nowadays. One of the most dominant applications is the nociception-analgesia balance. Some evidence support that heart rate variability correlates with perioperative stimulation and postoperative pain score. There are some new evidence support EEG correlated with anesthesia depth and analgesic balance. However, the heterogeneity between the studies and interference factors has limited their usage in clinical practice. On the other hand, peripheral nerve block is broadly used as a routine technique with general anesthesia, but few studies discuss the effect on heart rate variability. Our study focuses on the different HRV and EEG patterns of incision and insufflation during laparoscopic surgery with general anesthesia. Furthermore, we measure the effect of transversus abdominis plane nerve block to heart rate variability during surgery. By this comparison, we can discuss the influences of somatic stimulation, visceral stimulation, and pneumoperitoneum to heart rate variability, and then improve the accuracy of HRV-based nociception-analgesia monitors.
